2: Thevenin Battery model, the drawbacks of Thevenin based electrical model are that all elements are considered to be constant but they are not constant4. Resistive thevenin Battery model, this model is having some assumptions these are: ' constant current is drawn during discharging ' constant electrolytic resistance during discharging ' porous materials are used for electrode. Resistive thevenin battery model is given by4: Fig. 3: Resistive thevenin Battery model. In this model, two internal resistances battery and are used for charging and discharging. Two diode are used out of which only one forward biased and other one in reverse biased at a time. It depends upon the process of charging or discharging.

This model seems very simple but it is does not depend upon the state of charge (soc changes in online internal resistance esr due to temperature branding and electrolyte concentration. This model never is used for monitoring of battery in Electric vehicle. It is applicable in specific circuit simulation where power is assume to be unlimited1. Modified Battery model, it is the improve model of simple battery model. In this model, the disadvantages of above model was considered and make a propagate model. Here battery internal resistance esr changes according to changes occur in state of charge over the time. A common formula is set and given as: (1 at fully charged condition, internal resistance of battery was calculated and (2 where, is 10 hour battery capacity(Ah) at reference temperature ( it may be change according to battery age). S is changes from 0 when battery is completely discharge or 1 when battery is completely charge. The coefficient k is function of discharge rate of battery and it is calculated by, and basis which can be determined by curve given by manufacture3. Thevenin Based Electrical Model. This model is consisting of ideal no load battery voltage, capacitance c occur due to capacitance of parallel plate3, internal resistance and over voltage resistance occur due to the contact resistance of plate to electrolyte shown in fig 2: Fig.

Different Types of Battery model. There are many techniques of battery modelling are present. Few of them are mentioned here with their merits and demerits are given below:. Simple battery model, it shakespeare is the most common model of the battery. This model is having a terminal voltage and internal resistance of battery which is equivalent to constant internal resistance esr with open circuit voltage. It is consisting of ideal battery which having unlimited power is assumed shown in fig. 1: Circuit of the simple battery model. At fully charged condition, the terminal voltage is obtained from open circuit measurement. Esr can be obtained by connecting a load and by measuring the voltage and current across the load.

' Batteries are used in Uninterrupted Power Supplies. There are many parameters related to battery modeling like internal resistance, discharge type and discharge mode. Internal resistance consisting of Self-discharge resistance, resistances for Charge and Discharge and overcharge and over-discharge resistance. In discharge type one is Continuous Discharging in which battery gives the energy to load without any rest plan and other is intermittent discharging gives the energy to load for a period due to which voltage recovery take place cause increase in voltage. Discharge mode is consisting of constant load, constant current, constant power and rate of charge/discharge. High rate of charge/discharge decrease the battery life. A controlling method is used to avoid deep discharging of battery as well as reduce the charging and discharging cycle of battery1. It will improve the state of health of battery. Self-discharge, battery storage capacity, over voltage and internal resistance represents behaviour battery parameters2 and a model explain non-linear characteristics of battery in terms of state of charge3.

This paper gives the brief information of battery models. Moreover merits and demerits of these battery models are summarized. 1- Introduction, battery is used to store energy basically its convert chemical energy into electrical energy or vice versa. This property of battery is very useful in power system. It has used everywhere for availability of energy. Some of its main applications are grown in last decade of year, these are: ' Battery is in Electrical vehicle1. ' For the energy storage in plant we use battery Energy Storage Plants. In this we compensate the flow active or reactive power.
